any tell me  i got compile on dataskop but when got any new fix or any new rev i need only update MMCore and replace this 2files on GameServer and Login ?

You have to update your l2jserver.jar and datapack. And ofc its depened from what changes were made (im talking about Commits etc.)

wher can find l2jserver.jar ?

l2jserver.jar is main compiled jar... its compiled GameServer (+configs and others)

ok tnx
